I put in a small pond this winter and want to get a few plants for it. Who
in town (or online) has good selection/quality/prices?

I second going to Hill Country Water Gardens (or something like that), on
183 all the way north in Cedar Park.

Also, any plant suggestions? It gets pretty good sun, but some midday
shade. It's half moon shaped, 7' long, 3' wide, 3' deep in the center, with
1' ledges on the tips. I also have a hypertufa veggie filter (sans veggies
at the moment) 1.5'x2.5'x1.5' deep that spills over into the pond.

Lillies are a common choice. Choose hardy ones.

What's an appropriate fish stocking rate for this size pond and should I
wait until later in the year to add fish?

For goldfish (or koi, but beware, koi will eat your plants) the usual
rate is 10 gallons per inch of fish. The fish are measured from the tip of
the mouth to the base of the tail.
